XC6220B331MR 是 TECH PUBLIC(台舟电子)推出的一款高性能低压差线性稳压器(LDO),采用 SOT-23-5 小型封装,提供固定 3.3V 输出,最大输出电流可达 900mA。器件集成过流保护与过热保护,静态电流仅 25µA,适合需要低静态功耗且对输出噪声有较高要求的便携与工业应用场景。
XC6220B331MR 在中高电流输出范围内仍保持较低的压差,使其在电源输入电压较低时依然能够提供稳定 3.3V 输出。50dB 的 PSRR(10kHz)表明本器件可以有效抑制来自 DC-DC 变换器的开关噪声,适合用于以开关电源为主供电但对 3.3V 轨要求低噪声的模拟/数字混合系统。
25µA 的静态电流是该器件一项重要优势,适合对待机功耗敏感的便携式设备、物联网终端、无线模块及电池供电系统。当系统需要高达近 1A 的瞬时负载能力时,XC6220B331MR 能提供相应支持,同时内置保护机制保障器件与系统安全。
总结:XC6220B331MR 是一款适用于多种应用的高 PSRR、低静态电流、中高输出电流能力的固定 3.3V LDO。合理的 PCB 布局与散热设计能够充分发挥其特性,为对噪声、待机耗电和可靠性有要求的系统提供稳定的电源解决方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
